by the lithium‐catalyzed anti‐Markovnikov selective intermolecular hydroamination reaction of secondary aliphatic amines with vinylarenes. The use of only 1.5 mol % LiCH2TMS as a solid base in THF proved to be efficient to deliver the target products at room temperature with up to complete conversions. Both reaction partners were, moreover, used in equivalent amounts; thus, this protocol best respects
通过仲脂族胺与乙烯基芳烃的锂催化抗Markovnikov选择性分子间加氢胺化反应,可以直接获得各种β-芳基乙胺衍生物。事实证明,仅使用1.5 mol%的LiCH 2 TMS作为THF中的固体碱,可以有效地在室温下完成目标产物的转化,直至完全转化。此外,两个反应伙伴的用量相同。因此,该协议最好地遵循了可持续化学的概念,以便轻松制备用于药物活性化合物的前导结构。
